I think it is an interesting thought and maybe true in some ways. I do like the wider choice in women's fashion but I never thought of going into bat for a winning team. For me that would be ridiculous and I never would have even thought about that when I was a child dressing.
I personally think the internet, forums, and online shopping has provided many with a knowledge that they are no longer alone. To promote that idea as a contributing factor may be correct for a few but I fear that the more way out and ridiculous ideas that are promoted as a minority query may have consequences that support some underlying view concerning some other issues. Just another knock for us who dress and behave femininely and seek acceptance.
Maybe the person had a few too many wines or came up with an idea that has not been validated the evening before the radio program. I would have thought that on radio she would have first questioned the idea amongst her colleagues as part of research material in order to air it in the public domain.
She maybe inexperienced too and has opened herself up to criticism to promote herself within her area of expertise. Controversial and alerting to again put a rift between the sexes and those who bridge the two.
